The conditioning of the electrode is a two-step process in which the glass is etched then rehydrated. The first step is etching. This process removes a thin layer of sensitive glass from the sodium membrane, exposing a sodium-containing fresh surface. The second step is rehydration in which the probe is placed in storage solution to rehydrate the glass membrane. Allowing the glass to rehydrate after etching provides optimum conditions for the exchange of sodium ions between the membrane and solution.\u003c\/p\u003e\n\u003cp\u003eFor the FC300B to measure sodium accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the sodium ionic strength adjuster (ISA) solution. The sodium ISA is important for two reasons. One is that the ISA buffers the pH of the standard and sample to above pH 9.8. This removes any interference from hydrogen ions that occur at lower pH's. The second purpose of the ISA is to ensure that the activity coefficient is constant so the concentration of free sodium ions can be measured. Having solutions with a constant ionic strength reduces the margin of error between measurements of different samples at different concentrations.\u003c\/p\u003e\n\u003cp\u003eThe FC300B sodium glass ISE can measure from 10µM (0.23 mg\/L) to 1M (22, 990 mg\/L).\u003c\/p\u003e\n\u003ch2\u003eConversion Table for Na\u003csup\u003e+\u003c\/sup\u003e and NaCl\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x: auto; margin: 0 0 32px;\"\u003e\u003ctable rules=\"all\"\u003e\n\u003ccolgroup\u003e \u003ccol width=\"437\"\u003e \u003ccol width=\"171\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003eMultiply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003emoles\/L (M) Na\u003csup\u003e+\u003c\/sup\u003e to ppm (mg\/L) Na\u003csup\u003e+\u003c\/sup\u003e\n\u003c\/td\u003e\n\u003ctd\u003e22990\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eppm (mg\/L) Na\u003csup\u003e+\u003c\/sup\u003e to M (moles\/L) Na\u003csup\u003e+\u003c\/sup\u003e\n\u003c\/td\u003e\n\u003ctd\u003e4.35 x 10\u003csup\u003e-5\u003c\/sup\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eppm (mg\/L) Na\u003csup\u003e+\u003c\/sup\u003e to ppm (mg\/L) NaCl\u003c\/td\u003e\n\u003ctd\u003e2.54197\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eppm (mg\/L) NaCl to ppm (mg\/L) Na\u003csup\u003e+\u003c\/sup\u003e\n\u003c\/td\u003e\n\u003ctd\u003e0.39339\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003ch2\u003eFeatures at-a-glance\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eSpherical Glass Tip\u003c\/strong\u003e - The spherical shaped tip design allows for a wide area of contact with the sample, permitting a faster electrode response with a higher degree of stability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGlass Electrode Body\u003c\/strong\u003e - The glass electrode body is suitable for a wide range of applications due to its chemical resistance.

The pKa of the ammonia\/ammonium relationship is 9.24; thus, at a pH of 9.24 there will be an equal concentration of ammonia and ammonium. As pH decreases, becoming more acidic, the concentration of ammonium increases and ammonia decreases. The opposite occurs as the pH increases.

The skirted cone geometry of the sensor forms the liquid junction with the test solution at the tip of the junction cone, producing a highly stable reference potential and consistent flow rates of electrolyte into the solution. A simple press of the top portion of the ISE makes it easy to empty the electrolyte fill solution and replace when necessary.\u003c\/p\u003e\n\u003cp\u003eFor the HI4114 to measure potassium accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the potassium ionic strength adjuster (ISA) solution. The ISA ensures that the activity coefficient is constant so the concentration of free potassium ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements.
